Judo Throws and the Resemblance to Koryu

I was curious as to the resemblance of Judo throws to their koryu origins. Are the throws well preserved from their lineage, or have they greatly changed? Was there as much emphasis on the jacket (as in Morote-Seoi-Nage) as a source of contact for the throws as in their koryu counterparts?

Many throws were similiar if not the same. For example, Osoto Gake is found in numerous Ko ryu . However, throws like Seio Nage become a bit impractical when one's opponent is wearing 80 pounds on armour. That is where throws such as Ganseki Nage is more usable. When the end of the warring states and the fact people stopped wearing armour, the more Ko Ryu throws were turned into more modern Judo.

I might post again when I haven't been up for 20 hours straight and didn't just get back from a 4 hours Koppojutsu and Kenjutsu session.

The major differences between Judo throws and their Koryu counterparts can be boiled down to intent and mechanics. Judo throws are designed to allow fellow practitioners to catch breakfalls by landing them squarely on their backs and will most likely incapacitate an unskilled "victim" of such a thrown rather then kill them. Many koryu throws are built around landing the opponent in such a fashion that it either severely incapacitates them or straight out kills them by preventing them from being able to make any form of breakfall. These separate intents change the mechanics of the throws.

The most Koryu looking material in Judo is contained in the now rarely practiced Koshi-no-kata which Kano formulated to preserve elements of Kito-ryu techniques thought it was definately "Kano-ized for safety." You can see Kano* engaged in portions of this kata at

Now go and convert another and see if you can start some kind of non-compliant Judo kata training movement.

(In answer to your question, mostly sleep loss)

Bringing back the "randori" in Randori no Kata? Kinda tough for a gokyu, don'tcha think? Either way I'm seriously thinking about adding Nage no Kata into my fellow Kyu's and my informal weekend trainning sessions. (The one good thing about being the former "junior sensei" of a krotty McDojo that I now sponsors a seperate Judo Club who needs the matt space which I switched to.... I have the keys to the Dojo:walk: )

Welcome to Bullshido.net: Japanophiles Section. And I don't think Judoka have forgotten these forms, but rather since they're basically used as tradition and grading and formality (not saying that's what they are, but the fact is that's what they've basically become to most Judoka) that the just don't really bother with them and have replaced the forms with Uchi Komis, that's all.
